Unknown HS2 problem when communicating with Thrift server.

Expert Contributor

I am getting this error in Hive queries.CM shows hive service is up and running just fine without any exits. Recently had connected to Hive through Tableau as well. Usually happens around the same time in morning,

 

 

How do I fix this? What could be the issue? No heavy processing on server when this happens. very few and small queries running at the time it happens.

So is this intermittent issue? It looks like launcher is not able to connect to HS2, when this happens, can you connect to HS2 from other hosts?

Are you able to share the workflow.xml file?

Do you have kerberos enabled in the cluster?

Hi @EricL 

 

This happens due to the hive server is not working or stopped due to some problem.

 

Restart the hive server with the below command and try again.

 

hive --service hiveserver2 &
